Abbreviationb Type of treatmentc Surface finish Notes Hot rolled 1C Hot rolled, heat treated, not descaled Covered with the rolling scale Suitable for parts which will be descaled or machined in subsequent production or for certain heat-resisting applications.
1E Hot rolled, heat treated, mechanically descaled Free of scale The type of mechanical descaling, e.g. coarse grinding or shot blasting, depends on the steel grade and the product, and is left to the manufacturer's discretion, unless otherwise agreed. 1D Hot rolled, heat treated, pickled Free of scale Usually standard for most steel types to ensure good corrosion resistance; also common finish for further processing. It is permissible for grinding marks to be present. Not as smooth as 2D or 2B. Cold rolled 2C Cold rolled, heat treated, not descaled Smooth with scale from heat treatment Suitable for parts which will be descaled or machined in subsequent production or for certain heat-resisting applications.
2E Cold rolled, heat treated, mechanically descaled Free of scaleg Usually applied to steels with a scale which is very resistant to pickling solutions. May be followed by pickling. 2D Cold rolled, heat treated, pickled Smooth Finish for good ductility, but not as smooth as 2B or 2R. 2B Cold rolled, heat treated, pickled, skin passed Smoother than 2D Most common finish for most steel types to ensure good corrosion resistance, smoothness and flatness. Also common finish for further processing. Tension levelling may be used as an alternative to skin passing. 2R Cold rolled, bright annealed d Smooth, bright, reflective Smoother and brighter than 2B. Also common finish for further processing. Special finishes 1G or 2G Grounde See footnote f Grade of grit or surface roughness can be specified. Unidirectional texture, not very reflective.

Non-directional finish, reflective with high degree of image clarity. 2F Cold rolled, heat treated, skin passed on roughened rolls Uniform non-reflective matt surface Heat treatment by bright annealing or by annealing and pickling. a Not all process routes and surface finishes are available for all steels. b First digit, 1 = hot rolled, 2 = cold rolled. c The basic heat treatment condition specified in the relevant Table 7, 8, 9 or 10 applies. d May be skin passed. e One surface only, unless specifically agreed at the time of enquiry and order. f Within each finish description the surface characteristics can vary, and more specific requirements may need to be agreed between manufacturer and purchaser (e.g. grade of grit or surface roughness). g Different methods of mechanical descaling may be used. Shot blasting will result in a rough and dull surface while brushing may result in a smooth surface. SIST EN 10028-7:2016
